Christmas Creek, Western Australia Investor Presentation | RRS Gather Round | April 2026 2 Christmas Creek Manganese Discovery A Potential Company Maker? Field work targeted REE (not Mn) based on radiometric anomalism Extensive black outcrops discovered and samples taken Extremely high-grade rock chips in first pass outcrop sampling Outcrop showed scale, with ~750m of continuous Mn in an area 750 x 400m, constrained by recent sand cover 58.37% Mn Sample ID TKMCCR2506 https://trekmetals.com.au/announcements/7259499 3 Immediate Follow-up to Assess the Potential 1. Gravity 2. AEM/Mag 3. Sampling 4 Additional Rock Chip Sampling 59.65% Mn Sample ID OS0063031 56.7% Mn Sample ID OS0063065 5 Discovery Outcrop 6 View to the East 7 View to the West 8 Geophysics Indicates Significant Scale Potential Beyond the Outcrop High dry bulk density average of 4.03 g/cc (3.31 - 4.47 g/cc) from representative rock chips Manganese-rich material at depth likely to present as a gravity high https://trekmetals.com.au/announcements/7311646 Gravity data shows a good correlation with the known outcrop Data also shows significant anomalism that extends well beyond the outcrop Second‘northern’trend identified under cover… could it represent more manganese? 9 Additional Rock Chip Sampling Assays Confirm Extensive High-Grade https://trekmetals.com.au/announcements/7326226 Assays average 50% Mn, confirming high-grade nature of mineralisation Grades up to 60.1% Mn (approaching theoretical maximum in Mn-oxide) Only one question remains: How much is down there? Drilling set to commence in April to answer this question! Manganese-rich sample 56.7% Mn Sample ID OS0063065 10 Manganese Fundamentals Grade Matters A critical mineral hiding in plain sight ◆ Essential for steel production (~90% of global Mn demand) ◆ Increasingly critical for lithium-ion batteries (NMC, LFP, LMFP) ◆ Designated a critical mineral in multiple Western jurisdictions Manganese Pricing ◆ Current manganese price of ~US$5.58/dmtu*^ for 38% material, which equates to US$212 per tonne of ore ◆ Manganese is approximately 2x as valuable as iron ore (~US$107 per tonne of ore^) Grade is king ◆ >44% Mn ore trades at a significant premium to lower-grade material ◆ Only two high-grade producers in Australia: Woodie Woodie (ConsMin) & Groote Eylandt (S32) *A Dry Metric Tonne Unit (dmtu) represents 1% of a dry metric tonne. Price conversion to AU$/tonne for ore grading 38% Mn is US$5.58 x 38% = US$212/tonne, converted to AU$ x 1.45 = AU$307/tonne. ^Price sources: Manganese: Shanghai Metal Market & Iron Ore: Market Index 11 Thorough Land Surveys Equate To Better Planned Drilling 70 Planned Priority 1 Drill Holes for 9,100m 100m - 150m Drill Line Spacing Selected 50m Spaced Drill Holes Targeting Gravity Highs and Down Dip Extensions of High-Grade Manganese Mineralisation at Surface Scope for follow-up drilling based on results 12 Location Kimberley Region ◆ Kuro sits 50km south of the Great Northern Highway ◆ Three ports with bulk handling facilities nearby (Derby, Wyndham & Broome) ◆ 5,608km² new tenement applications Distances Kuro → Highway 50km Kuro → Derby 480km Kuro → Wyndham 563km Kuro → Broome 622km 13 Activity Q4 2025 Jan-26 Feb-26 Mar-26 Apr-26 May-26 Jun-26 Q3 2026 Q4 2026 Kuro Mn discovery announced Significant gravity response announced Confirmed high-grade geochemistry announced Capital raise to support exploration completed New exploration tenure pegging completed Planned Mn heritage survey Planned Mn geophysical surveys Planned Mn exploration drilling phase 1 Planned Mn metallurgical drilling Mn exploration drilling Phase 1 results Planned Au & Au-Cu exploration drilling Commencement of metallurgical test work Activity Timeline 14 15.18% CORPORATE SUMMARY Strong Balance Sheet, Leveraged to Success Capital Structure ASX Code TKM.ASX Share Price (1st April 2026) $0.170 Ordinary Shares 716.38m Unlisted Options ($0.225 exp 24 Feb 2028) 7.86m Performance Rights 44.72m Market Cap. $121.78m Cash and cash equivalents (31st Mar 2026 - unaudited) $14.63m Debt nil Enterprise Value $107.15m Share Price and Volume Board & Management 68.19% Top 100 Holders 0.0 M 1.0 M 2.0 M 3.0 M 4.0 M 5.0 M 6.0 M 7.0 M 8.0 M 0.00 0.05 0.10 0.15 0.20 0.25 Mar-25 Apr-25 May-25 Jun-25 Jul-25 Aug-25 Sep-25 Oct-25 Nov-25 Dec-25 Jan-26 Feb-26 Volume Closing Share Price (A$/share) Volume Close 15 A Rare Opportunity at an Early Stage High-grade Rock chip assays average ~50% Mn, up to 60.1% Mn Premium manganese (>44% Mn) is rare and drives value Large, under-explored system Extensive >1,200km² package of highly prospective, under-explored ground Potential for multiple manganese positions Clear near-term catalyst Maiden drilling scheduled to commence in May Designed to test grade, width and depth & provide metallurgical samples Scale potential 750m of continuous, high-grade manganese at surface Strong gravity response indicates significant scale beyond the outcrop 16 Join us on the Journey The right team ◆ Proven track record in discovery, delivery & serious value creation ◆ Pilbara Minerals (ASX:PLS) lithium discovery and project delivery driven by the current TKM board from penny stock to >AU$15B market cap* ◆ Deep global connections, especially in the lithium-ion battery market Source: https://www.marketindex.com.au/asx/pls.
